Electron Impact Excitation Collision Strengths for EUV Lines of Fe VII

New extensive calculations are performed for electron collision strengths, rate coefficients and transitions probabilities for the astrophysically important lines in Fe VII. The collision strengths were calculated in the close-coupling approximation using the B-spline Breit-Pauli R-matrix method. The multiconfiguration Hartree-Fock method with term-dependent non-orthogonal orbitals is employed for an accurate representation of the target wave functions. The close-coupling expansion includes 189 fine-structure levels of Fe VIII covering all possible terms of the ground $3p^63d^2$ and one-electron excited configurations $3p^53d^3$, $3p^63d4l$, $3p^53d5s$, and $3p^63d5p$. The effective collision strengths are obtained by averaging the electron collision strengths over a Maxwellian distribution of velocities at electron temperatures in the range from $10^4$ to $10^7$ K. There is an overall good agreement with the previous R-matrix frame-transformation calculations, but significant differences are also noted for some transitions. The corrections to the previous results come mainly due to more extensive expansions for the Fe VII target states.
